On Strato Pi Base, UPS, CAN, CM and CM Duo, the STRATO I/O Server requires the [https://github.com/sfera-labs/strato-pi-kernel-module Strato Pi Kernel Module] to be fully functional. Without the kernel module, only a subset of the features are available for backward compatibility.
 +
 +
Strato Pi Fan is also supported if the [https://github.com/sfera-labs/strato-pi-fan-kernel-module Strato Pi Fan Kernel Module] is installed.

The Strato I/O Server implements all data points provided by the underlying Strato Pi kernel module. Refer to the documentation available at [https://github.com/sfera-labs/strato-pi-kernel-module Strato Pi Kernel Module].
 +
 +
Each readable file name exposed by the kernel module under the /sys/class/ionopimax/ sub-directories appears as a data point with id <subdir>.<file>. For example, as the buzzer's status file is /sys/class/stratopi/buzzer/status, the corresponding data point is "buzzer.status".
 +
 +
Command files that are marked as write only in the documentation (W), are not shown as visible data points in HSYCO, but can be used in the IO events action or ioSet() methods to send a command.
 +
 +
For example, if "strato" is the id assigned to the Strato I/O Server, then:
 +
TIME : IO strato.buzzer.beep = 1000
 +
will make the buzzer beep for 1 second (1000 ms).
 +
 +
Note that "strato.buzzer.beep" is not visible in the Status Browser and doesn't generate events, because it is write only, and only the "strato.buzzer.status" data point will be visible, with a value of 0 if the buzzer is not active, or 1 if active.

Strato Pi is an expansion board developed by Sfera Labs for the Raspberry Pi computer.

Strato Pi

Strato Pi implements a number of hardware features to expand the Pi and allows its use in professional applications:

  • 9-28 Vdc extended-range power supply
  • integrated UPS with external NiCd rechargeable battery
  • real-time clock with dedicated back-up battery
  • opto-isolated RS-232, RS-485, CAN bus ports
  • configurable hardware watchdog
  • buzzer for audible feedback.


HSYCO Configuration

Add a STRATO I/O Server in the I/O Servers section of the Settings and set its parameters.

Note that the Strato I/O Server doesn't count in the I/O servers license total, so you don't need an extra I/O Server license to use Strato with HSYCO.


On Strato Pi Base, UPS, CAN, CM and CM Duo, the STRATO I/O Server requires the Strato Pi Kernel Module to be fully functional. Without the kernel module, only a subset of the features are available for backward compatibility.

Strato Pi Fan is also supported if the Strato Pi Fan Kernel Module is installed.

High Availability

  • Shutdown when inactive: defaults to false.

Options

ID Default Values Description
dualsdsync false true enables the files synchronisation process that copies all HSYCO files and some operating system configuration files to the alternate SD card (SD1). Synchronisation occurs automatically once a minute. SD1 is enabled and its root file system mounted to /mnt/alt
false disables the files synchronisation process
manual doesn't change the watchdog configuration parameters
watchdog always
(false on Strato Pi Mini) 		always enables the hardware watchdog and automatically generates the heartbeat signal (when the HSYCO main control loop is running normally, approximately every 10 seconds). The watchdog timeout is set to 60 seconds while HSYCO is running, or to 1 hour when HSYCO is manually stopped (sysctl stop hsyco) and when it is starting. If dualsdsync is set to true or manual, the watchdog is configured to boot from the alternate SD card if there is no heartbeat after the first reboot
true enables the hardware watchdog only while HSYCO is running, and automatically generates the heartbeat signal (when the HSYCO main control loop is running normally, approximately every 10 seconds). The watchdog timeout is temporarily set to 1 hour when HSYCO is starting. If dualsdsync is set to true or manual, the watchdog is configured to boot from the alternate SD card
false disables the hardware watchdog
ignore doesn't change the watchdog configuration parameters
shutdown_minutes 0 0 no automatic shutdown after power failure
int > 0 the driver will command the operating system shutdown and hardware power off after N minutes of back-up battery operations during a power failure. The Strato board will automatically power-up the Pi when power is restored (use this option only with the Strato UPS board)
quiet false true enables audible alarms on power failure
false disables audible alarms on power failure
version base

Datapoints

The Strato I/O Server implements all data points provided by the underlying Strato Pi kernel module. Refer to the documentation available at Strato Pi Kernel Module.

Each readable file name exposed by the kernel module under the /sys/class/ionopimax/ sub-directories appears as a data point with id <subdir>.<file>. For example, as the buzzer's status file is /sys/class/stratopi/buzzer/status, the corresponding data point is "buzzer.status".

Command files that are marked as write only in the documentation (W), are not shown as visible data points in HSYCO, but can be used in the IO events action or ioSet() methods to send a command.

For example, if "strato" is the id assigned to the Strato I/O Server, then: 

TIME : IO strato.buzzer.beep = 1000

will make the buzzer beep for 1 second (1000 ms).

Note that "strato.buzzer.beep" is not visible in the Status Browser and doesn't generate events, because it is write only, and only the "strato.buzzer.status" data point will be visible, with a value of 0 if the buzzer is not active, or 1 if active.

Additional datapoints
